SHINGLE.

Application flled September 21, 1925. Serial No. 57,485. i

-This ,invention relates broadly to roof coverings and the like while it is more particularly associated with the fabrication of a novel type of shingle from Sheet material treated with weather-proofing substance to render the'sa'me impervious to the ravages incident to 'constant'exposure An object of the present invention is to ing b heavy winds or other causes.

A stlll further object is to provide shingles of the' above designated .typejwhich give added protection against fire hazards that may originate thereunder. I

Vith theabove stated-and other-objects in view, the. present 'invention'essentially consists in the matters hereinafter fully described, typically exemplitiedby the accompanying' drawings, and Voircuniscribed as ,to subject-matter, as well as scope, by the subjoined claims. i

In the drawingsz- F ig. I, is a viewin plan showing the. blank from which my novel type of shingle is formed, and also indicating, by dot-and-dash Outline, the manner in which it is severed from standard width material'- without waste.

Fig. II, is a face view of th finished` shingle. A

Fig. III, is a rear view of the same.

Fig; IV, is a top plan view of a fragmentary portion of'a roof coveredwith my novel type of -shingles; and, I

Fig,` V, is a. section taken approximately on' the line V-V in the preced'ing view Referring more infdetail to'the several views, wherein the same or corresponding parts are designated by llke reference mdices, land in carrying'out my invention, I preferably make use of sheet material-such as roofing feltrendered flexible, non-porousv and weather proof in accorda'ncewith customary practice. Such 'a sheet or length of material is indfiicated at 6, in Fig. Land it is preferably or a width to accommodate the dept-h of shingles're uired, and finished on i provide a novel form of shingle which, when fOne side with a suita le minera-lized.surfac-l laid, affordsa uniform multi-ply-'thickness ing imbedded therein. This length or 'roll of roofing material 6 is transversely severed at 4regular intervals to"provide individual shi'ngle blanks 7 thatareconsecutively cut in `revers'e`V relation without waste, as shown.

Each' aforesaid blank 7; las best appreciated from Figs. I-III; comprises a body or substantially-,square shingle 'portion 8 minus the upper diagonal corer'that provides a straight edge` 9; a pair of fiankingti'iangular portions V10, 10 foldable along creasings 11 alignin with 'the lower shingle side-e'dges 12; 'an a butt-tab 13 retroverted 'along a basal .creas'e 14 While separat'ed from the triangular portions 10, 10 by Verticalv inci'sions 15, 15. The lflankiinlz; triangular-portions 10, 10, it willl be remarked, areof a' superficial configuration, so that, when retroverted alongthey creases 11 against the 'underside- -or non-mineralized surface of the body portion 8, their bases '16 register with-the Vertical median line thereof with their free 'inclined edges 17 moved into parallelism' vre'lative to the upper'side edges 18 of. said shingle. In other words, the foldedshingle 8 becomes two-ply for` the major portion of .its 'area with a triple-ply at 'that'portion constituted'by the retroverted butt-tab '13. Attention is also directed to the `fact that the major portion of the shingle underside is' protectedand fireproofed-by the mineralized surfacing of the underfolded fianking `portions 10, 10. i w.

Shin les formed and configured asabove .set fort are laid in the following manner A starting strip 19 is first 'attached-to a straight vor longitudinal` edge of the roof. or` other ;surface boarding 20v in conformity with known practice, whereupon a succession of shingles 8 are. conveniently secured infplace by nailsf-not shownwith thebutttabs 13 forced below said starting. strip, and

their lnontiguous rectangular corners 21 in register; or, all such Corners 'of the first row are rranged in'direct alignment. Thus it will be readily vunderstood that the upperv straight edges 9 of the first row of shingles 8, so laid, will-likewise-be in direct lalign'- ment. The 'second or` succeeding row of overlappin `shinges 8 'is laid by nserting Y' the butt-ta '13 ,of each 'consecutive shingleV underneath'the contiguous rectangular corners 21 of av subjacent pair of shingles and aligning the upper side edges 18 thereof With therelative1y lspaced obtuse-angled corners 227ofsaid subjacent air of shingles; or, in

staggered relation-re ative to the fir'st mentioned row. Nai1s`orother attaching means44 are then applied where necessary or deemed essential. i It will, therefare, be readily understood that the individual shingles 8 are interengaged and securely locked against any tendency to lift .under wind or other pressure's; while all the exposed ed es thereofexcepting those at the ends o the surface covered-are constituted by folded material at the creasings 11, 11 and 14. This feature of my invention is deemed of considerable importance inasmuch as it effectively protects all the raw or severed 'edges from deterioration ,incident 'to climatic exposure.

' Again, the multi-ply thickness affordedby 'the pre-ordered connectionof the respective shingle units above set forth' greatly envhances the shadow-line effects, as will be ;i'clearly .apparent'to those acquainted with the art. i Successive overlapping rows of the shinges 8 are similarl laid and nailed in .sta gered diagonal re ation, in accordance I common practice until the entire roof or othersurface is covered and fimshed in the known manner; while attention is directed to the fact that the obtuse-angled corners 22 afford alignin points for successively laid superposed s ingles, as will be I obvious from an examination of Fig. IV.

Having set forth-the manner of fabricatingand laying my novel shingles attention is now directed to'some of the leading advantages inhering thereto. In the first place, it wii be apparent that the entire surface covered with shingles 8 is-of a minimum double-thickness throughout with a substantial 'mineralized inner surfacing as a prof tection against fire originating under the roof deck or the like.v Secondly, all weather exposed edges being coated and surfaced, are

-thoroughly protected from deterioration.

w .'Furthermore, the shingles 8 may be made from` relatively ,thinner stock than ordinarily used in the art whileafording a better protective covering without materiallyf increa'singv the weight per square From the foregoin 'it will be apparent that my novel t pe o shingle fully justifies the objects set orth in the statement ofinvention, and while is preferable to employ tion to accord with indivi the embodiment illustrated, it is to be'understood the same issuscetible of modifica'- ual requirements.

Having Vthns described my'invention I claim' 1. A shingle having a butt-tab and'f1ank-- ing foldable portions which, when retroverted, substantially convert said shingle to double-ply thickness.

2. A shingle having a bntt-tabv and fianking foldable' portions, said foldable'portions when retroverted forming a double-ply thickness shingle with upper-flanlring single-' ply portions and of triple-ply at the lower tip.

3. A shingle having a corner tab and flanking foldable portions, saidfoldable por-' tions whenl retroverted substantially backing the shingle, .and the tab overlapping the contiguous folds.

4. A flexible 'shingle having a corner tab' and triangular side portions, the latter when. retroverted substantially backing the shingle,

and the afore'said tab forming a looking tongue.

5. A one corner configured to afl'ord a rectangnlar butt-tab, and adjoining triangular foldable flanks, said flanks when retroverted hacking the shinglewith provision of upwardly merging single-ply portions.

point-down flexible shingle having- .6. A point-down flexible shingle having.

onecorner configured to afl'ord a rectangular butttab, and' adjoining triangular fold'able flanks, said flanks when. retroverted hacking the shingle Awith provision of upwardlv merging single-ply portions, and the butt-- tab overlapplng the continguous underfolds. 7. A fiexible shingle of substantially square outline having one corner removed blank embodying a substantially square body .n54

portion with a Ibutt-tab at one corner,- and blank embodying a substantially square body .110

when

retrovertible adjoining flanks which, when underfolded, substantially back said shingle With provision of' merging single-ply sections. a i

In testimonyf whereof, I have hereunto signedmy name at Maurer, New Jersey, thls 15th dayl of September, 1925. i
